on the nation, and even internationally. so there's a really keen awareness that you always have to be fixing the system. things corrode, they rust. they get to where you turn them on and nothing happens. but it is so totally used in every nook and cranny, that making any accommodation to shut it down, to do something to it, is very difficult. narrator: two massive underground tunnels, called simply tunnel 1 and tunnel 2, provide most of the city's water supply. they run hundreds of feet below manhattan, far deeper than the subways. built at the beginning of the 20th century, they are concrete-lined and bored through solid rock. they could last centuries. but the mechanical equipment within them will not. engineers in the 1950s
discovered rust on the tunnel's valves. there were concerns that if they closed the valves for tunnel inspections, they may never open again, leaving new york city without water. so they chose to keep them open. as a result, there has not been significant inspection, maintenance, or repair of the tunnels in decades. no one knows their current condition. hurwitz: currently, city tunnel 1 and city tunnel number 2 would be feeding each half of the city. so you'd lose half the city if you didn't have a replacement. narrator: without half of its water supply, the city would shut down. for nearly 40 years, new york has been in the process of constructing a solution. man: this project is water tunnel number 3. we started on this project in 1969. i'm a sandhog. i've been a sandhog for 37 years. narrator: sandhogs are the men of local 147,
who work deep below the city. they began building the infrastructure of new york in 1872. from the subways to the sewers, the water tunnels to the highway tunnels, new york city thrives because of their work. ryan: you got one little hole in the ground, and nobody knows we're here. see the empire state building, right. that's 1,000 feet. so you figure, you go down 1,000. how high that is -- that's how far we go down. narrator: stretching more than 60 miles under the city, tunnel 3 is taking generations of workers to complete.
ryan: i don't even want to imagine what my father had to go through. when we first started, it was a rough job. everything was dynamite. now, they have these machines called "moles." it's like a big drill, and it just cuts right through the ground. so there's no more dynamite. and it's still a rough job, but it's gotten to a point where it's a lot safer. in the '70s, we lost a man a mile basically. here, maybe we've had two or three deaths in the last 20 years, which is too much anyway, but it's cut down a lot. hurwitz: city tunnel number 3 will be an opportunity to take city tunnel 1 out of operation and rehabilitate it. city tunnel number 1 had one valve to shut off the whole tunnel. city tunnel 2 had two parallel valves. city tunnel 3 has 32, so there's much more redundancy.
lloyd: we're targeting a completion date of 2012 for tunnel 3. and we already are starting to prepare to take tunnel 1 offline. narrator: the construction of tunnel 3 is vital for maintaining the sustainability of new york's drinking water infrastructure. but the pipeline is useless if there's not a reliable supply of clean water within it. hurwitz: the city bought up land around the reservoirs to prevent it from development. it provides assistance to local residents to see that there's no pollution of the reservoirs. it's much more cost effective to prevent pollution and to protect a source of water than to remove it at the drinking water treatment plant. lloyd: what epa said to us was, "you can have an exemption from filtration "if you keep this undeveloped, "and if you can manage the wastewater so that it does not pollute your water supply." and we feel that we've reached the point
where we can really keep it clean enough to drink unfiltered for the indefinite future. and new york city is in a small club of cities that actually have that filtration avoidance waiver. narrator: while municipalities are responsible for maintaining systems and source supply, the standards that protect water are established at the federal level. there are two important pieces of federal legislation that were both enacted in the early to mid-1970s. the first was the clean water act, which acts to protect rivers and lakes, and sources of drinking water. the second was the safe drinking water act, that provides federal standards to assure the safety of the water that we drink. both acts have been amended since they were first adopted, and they're both cornerstones for the water issues
that we face in america today. allbee: the clean water act set a floor and basically said, "everybody's who's discharging "is going to have to have a permit, and to achieve this defined performance level." narrator: the clean water act regulates the discharge of pollutants into surface waters across the nation. it protects our watersheds, our recreational waters, and our drinking water intakes. man: today, more than 50% of the nation's waters are fishable, swimmable. that's almost doubled since the clean water act was passed in '72. narrator: another significant component of the clean water act was a federally funded grant program to build wastewater treatment plants to reduce pollution in the waterways. and many cities built their treatment plants with this grant money. oberstar: but even a decade after it was enacted, the reagan administration came in
and cut the grant program to a loan program. and funding diminished over a period of time. now, we still have 1/3 or more of the nation's streams and lakes that don't meet the standards of the clean water act. we have to advance the cause. that is the big challenge ahead of us. you just don't think of raw sewage in waterways in a developed country, and yet, that's what we have, and not just in pittsburgh, but all over. narrator: pittsburgh is situated at the confluence of the allegheny, monongahela, and ohio rivers. these three rivers are vital for industry, recreation, and drinking water. and each year, billions of gallons of combined sewer overflows discharge directly
into those rivers. hecht: we're now having to face the consequences of the choice that was made to put in combined sewer systems. narrator: in 1994, the government adopted a combined sewer overflow policy to reduce csos nationwide. cities with combined sewer overflows now face an enforcement action called a consent decree. under a consent decree, a city must reduce pollution levels significantly within a strict time frame or face heavy fines. in 1960, the combined sewer overflows were a perfectly legitimate way of dealing with sewers. woman: the mind set was that, what did it matter if we were sending our waste downstream? water was a good conveyance for pollution. man: sewer systems are installed to reduce public health problems.
now what you're doing is transferring the problem, you're transferring it to downstream cities. in addition, cities and towns above pittsburgh were doing the same thing. and then they were affecting the water intakes of pittsburgh. 90% of this region gets its drinking water from those same rivers that we have overflows occurring. hecht: we have sewage overflow with as little as 1/10" inch of rain. and our average storm here is a 1/4" storm. lichte: over a year's period, 16 billion gallons' worth of combined sewage and stormwater overflows into our rivers. tarr: it's not a problem of point "x" and point "y" alone. this is a watershed problem. a watershed problem. lichte: the watershed encompasses many municipal boundaries and it doesn't know any local politics. narrator: in the pittsburgh system,
83 cities and towns use the same sewage treatment plant -- alcosan. so all 83 municipalities have to work together to address the problem. schombert: we know we have billions of dollars that will have to be spent over the next 15 to 20 years. you can't do that wisely when you have 83 separate government agencies making decisions. the municipal consent orders and the alcosan consent decree require that the municipalities participate in a long-term, regional wet weather control plan. narrator: the information gathered in the initial research phase of the wet weather control plan will inform the large-scale infrastructure overhaul. and, as this research moves forward, pittsburgh is also working with environmental groups that are cleaning up the watershed. woman: make that connection. man: like a mural on the side of a building? woman: $5.00 to get in. man: there's water flowing under the ground right now. i really think a lot of people don't know that. that's a critical area, because everything that's
dropped on the ground is part of your watershed now. hecht: we have a very big focus on citizen engagement and community involvement. i'm thinking it's applicable beyond just this boundary. we see that as the most important long-term investment. man: you don't really get anything done until you start charging people. why not? they're not subsidizing or incentivizing that. hecht: every individual citizen is part of the problem and therefore every citizen has to be part of the solution. those are the street trees we want people to be planting. we do a lot of tree plantings. all of you must intuitively go, "of course it's good to plant trees," of course, i want to put a rain barrel on my house." but is there a measurable environmental impact? trees are going to take up a lot of stormwater over time and are kind of a long-term green investment. we've had more than 200 volunteers come out planting street trees. we need people to make active changes on their property. and to reduce the amount of flow that's going into the combined sewer lines, we're trying to install 4,000 rain barrels. narrator: homeowners can disconnect
roof gutter downspouts from the sewer system and divert the stormwater into a rain barrel. schombert: the rain water then can be used to water lawns and gardens and infiltrate back in the ground slowly, rather than being piped to a creek where it disappears moments after the storm's over. it's being held within the watershed and it helps regenerate ground water and stream flows. hecht: that's what we're going to do this afternoon is think about how to get more of those people involved. if there's less water in the streets, there will be less water in the pipes, less sewage overflow. narrator: in addition to mobilizing individual property owners, the watershed association undertook a project to restore the nine mile run stream in urban pittsburgh. schombert: the urban impacts on that watershed have been enormous. flooding flows, combined sewer overflows, gave it the nickname of "stink creek" for many, many years. hecht: before the stream restoration, when you have a rain event, the stream would just be
barreling, just filled with tons and tons of water, and the water would move very quickly, eroding the stream banks further. narrator: the rushing water ran all the combined sewage straight into the monongahela river, which is a main supplier of drinking water for the region. hecht: what has happened because of the restoration is the water overflows its banks, it floods into these nice flood plains with native plants. and then slowly the water percolates back down into the stream. narrator: this allows the land to naturally filter and clean the sewer overflows before they enter the river. the restoration included extensive environmental changes to improve the stream and infrastructure changes to reduce the csos into the watershed. hecht: when i first started talking with people about stream restoration, i kind of imagined people out with shovels and small-scale.
this is a massive $7.7 million project. schombert: nine mile run watershed is the most significant urban watershed restoration ever done in the united states. narrator: small-scale projects like nine mile run have far-reaching environmental impact. but they're just one part of the regional wet weather control plan. schombert: this region needs to solve its problem by 2026. that's not that long away. this is the largest public works project ever undertaken in this region. lichte: you're looking at significant infrastructure. either tunnels or storage tanks, or, you know, treatment facilities. the cost is about $3 billion. lichte: if you look at some of the other cities that have gone through this, their rates have gone up significantly. the federal government provides a number of grant programs but the bottom line is, you know, it's not enough. there's a massive need of money out there for wastewater and water infrastructure improvements
around the country. narrator: the struggle for funds is as great in small towns as it is in metropolitan areas. oberstar: the federal government has let down municipalities. the first investment under the '72 clean water act was to deal with the biggest waste streams. and after a period of six or seven years, to then go to municipalities under 250,000 population. but that was just about the time when the federal government converted to a loan program. so smaller-sized communities have had to deal with repayable loans. a larger cost on a smaller tax base, and, arguably, less affluent communities. man: sewickley township is a rural farming community, however, herminie itself would be considered to be the downtown area of the township. it's the agways, the auto-parts store, the bank.
it's your typical small-town village. man: people think that rural areas are pristine and perfect and everybody has a nice, simple life. that's, uh, not exactly the situation here. when you come into town in the summer, you know you're coming to herminie. woman: the aroma in 90-degree days... can sometimes just want to knock you over. woman: we have water. we have power, we have gas, but we have no sewage. i guess when they laid out the town years ago, it just all went into the pipes and straight into the "crick." sabljak: i've lived here 43 years in the same house. when i moved here, they told us that sewage would be here shortly. and here it is 43 years later and we still don't have it.
my husband and i went to the first meeting. he always said, "boy, i'll never see it in my lifetime." well... my husband passed away last december. man: right now, the wastewater in herminie is going to basically three places -- in the street, down mine shafts, or into the creeks. i think we're very lucky that we haven't had some kind of serious health problem. sabljak: i came up one morning to get my newspaper, and there was this pool of stench up here. there was a pipe spouting, like a fountain, with everything coming out. everything was on the road already. i could see toilet paper. i could see other things that were... that you would put in a sewer. mcmillen: well, i was actually born and raised in westmoreland county so i have been aware of the conditions in herminie all my life.
herminie has declined, because for any type of business of any size to come in and create jobs, they need the infrastructure there, and in herminie, it's just not there. narrator: to address community frustrations, sewickley township, home of herminie, created a sewer authority board in 1998. it's comprised of residents and business owners who worked for almost a decade to get sewage infrastructure for the area. miller: we were novices. i don't think anybody in the township knew where to go. and we were frustrated at times. we thought we were right on the cusp of getting funding, and then, something happened and we didn't get it. yeah, we could go out and float a loan, and probably people would be looking at maybe $100 a month in sewage bills. so what you have to try to do is get enough funding to keep sewage rates at a reasonable rate so people can afford them. and that's been a real problem. without grant money, it can't be done. mcmillen: they were in line, waiting for our money.
they had an application on my desk. but when someone has no funding, usually they sit and wait. the problem is, the amount of money given in the federal budget and the state budget is just not enough to fund infrastructure. we have a $200 million backlog on my desk alone. and that would be our entire state's allocation for 4, 5, or 6 years. schwartz: the usda asked that i go to herminie and provide an independent evaluation of the problems to determine if it was severe enough to warrant funding. i've worked in a lot of communities in pennsylvania, i've seen a lot of things that were pretty startling, however, the trip to herminie absolutely, um... astounded me. i wrote a letter to usda, saying that it was the worst thing i'd ever seen in pennsylvania and that if they could award funding, that they do so. and they did.
they did. over $15 million, grant and loan, for that project. mcmillen: and it took years to get funding. what kept this project going was the steadfastness of the community -- they knew they needed sewage, and they just kept plugging along till we got through every issue that came up. the project will consist of 44 miles of line that we're going to put in, and a treatment plant. it will permanently eliminate the problem, the health hazards. i anticipate a definite regrowth in herminie, and it will be a good thing for everybody. zdravecky: maybe it won't help me too much because i'm an old lady, but whoever comes along after me will get the benefit. schwartz: there's nothing isolated about the herminie situation. it's a very common problem. it's a town that was built before current standards. this is not backwoods rural america at all.
it's just an unfortunate situation that was created probably a hundred years ago or more. and the people have to pay for it in a big way now. because the government is choosing to spend its money elsewhere right now, there's very limited money for communities to install adequate drinking water and wastewater, and i think it's criminal. that's my feeling. this country has to get its priorities right, and they're wrong right now. narrator: herminie faces problems because of the way its residents laid out the town generations earlier. across the country, many other cities and towns deal with the unexpected consequences from their early infrastructure design. los angeles county is a land of sprawling development. with development comes hundreds of square miles of concrete, leaving no way for water to naturally soak into the ground. in areas of such widespread urbanization,
flooding can be devastating. man: back in early 1930s, there was a flooding that took a lot of lives and property. as a result, the city of los angeles, in order to protect future flooding in the city, they decided to take the los angeles river and make it a flood control channel. they concreted the walls of the river in order for water to get to ocean much faster. narrator: cities throughout southern california converted natural rivers to these concrete channels, part of their storm drain systems. this allowed expanding development without the need for large flood plains. kharaghani: the los angeles river is approximately 51 miles. concrete reduces the size of the river that you need to carry the water because it speeds up the flow of water. if you'd like to remove all the concrete and to have natural system to carry the water
to protect you from flooding, you need to have almost one mile on each side of the river set aside for transport of rain. so in order for the city to have use of those lands around the river, concrete made it possible to have minimum land so the water can be carried to the ocean in the fastest possible way. but, unfortunately, because of population growth and poor housekeeping, people are putting a lot of pollutants on the street and the streets are the openings to our stormwater sewer system. in an average year, 4,000 to 5,000 tons of trash ends up in long beach. man: we've created a system to deal with flooding but inadvertently created a pathway for pollution to get into our waterways. narrator: los angeles county is beginning to develop ways to reduce the infrastructure's impact upon the environment. on the front lines of protecting the beaches, are the crews that clean out the stormwater system.
man: this big vactor truck works on the same principle as your vacuum cleaner in your house, only this thing sucks up the whole house. some of the storm drains collect a lot of trash. i started cleaning drains in '93. they were horrible because they hadn't been maintained so much. now this is a priority. you have trash, animal waste, and it ends up on our beaches. that is a health risk. that is one of the main reasons why we have to close the beaches after heavy rain. narrator: but even when it's not raining, water still enters the stormwater system, carrying pollutants. here on the west coast, a lot of our storm drain systems are separate from the sanitary sewer system, so if you dump something in the storm drain, it goes right to the ocean untreated. alamillo: we haven't had a major rainstorm in the last year or so yet there's a lot of water in this creek here.
i would say 20% of it is natural and the other 80% is runoff. shapiro: the purpose of the smurrf is to treat dry weather runoff, which is coming from storm drains. dry-weather runoff occurs when people waste water through washing their cars in the street, hosing down sidewalks and parking lots, their irrigation systems overspray. narrator: in a city of 12 million people, those seemingly small bits of wasted water accumulate to enormous amounts. shapiro: so all that ends up in our streets, ends up in catch basins, storm drains, into our storm drain system, and for some of the city, parts of the city, it ends up here at smurrf. 350,000 gallons come here on a daily basis, producing recycled water, and that can be reused for landscape irrigation and indoor toilet flushing. the pumps can only handle so much water, which is generally when it's not rain, the dry-weather runoff, so if you get a storm of a decent size,
the pumps will shut down automatically and the water will just continue to flow out into the ocean and it carries a lot of bacteria and people can get sick when they're swimming in the water near a flowing storm drain. everyone knows you don't go in the water for 72 hours after it rains. you just don't. this is the dirtiest beach in southern california. doheny beach. i've surfed this twice -- i've gotten sick both times. narrator: san juan creek, a concrete flood control channel, flows directly to doheny beach. moriarty: the concrete you can almost think of as a big water slide for pollutants to go to sea level. man: if it rains more than 2/10 of an inch, the county puts out a health advisory for all beaches in the county. that totaled 75 days in 2006. so it's sort of a frightening thing that it's so polluted that every time it rains, we have to stay out of the ocean for three days. moriarty: to be sick after surfing isn't like,
"oh, i have a runny nose," and tomorrow it's gone. can be a lot of different things. nelsen: they include gastroenteritis, which is an upset stomach, and sinus infections, ear infections, eye infections, and there's also virulent versions of streptococcus that can actually cause severe illness and even death. moriarty: our goal with surfrider foundation is essentially to have the city understand that the water is, in fact, dirty, and then work with the infrastructure and the various issues to change that. narrator: but building more systems and more plants can't work alone as a sustainable solution. and, as in pittsburgh, as in new york, part of the answer lies in protecting the watershed. nelsen: we need to reduce the amount of impervious surfaces in our watershed, which are surfaces that don't let the water soak in and then create more pervious surface, whether it's by having driveways that allow water to soak in or different landscaping to try to eliminate
the amount of runoff that comes off our land so that the system, even with the development it has, acts more like a natural system and filters that water. water quality and sewage infrastructure isn't the sexiest of political agendas, but by raising the awareness about water quality issues, we can create political pressure to get our issues solved. about 15 years ago, surfrider activists were protesting a beach for being polluted. the city council asked the police to escort them away. there was complete denial of the problem. 15 years later, water quality is on the agenda of every city council person in that local city, and that's completely a result of activists forcing the issue, surfrider and other local groups, saying, "hey, these water quality issues are real and you need to address them." and only until the public sort of creates that will will the politicians respond. narrator: while some cities deal with infrastructure issues,
others have concerns about the sustainability of water supplies. allbee: it's not just about the sustainability of the assets, it's about the sustainability of our water resources. parts of this country that thought of themselves as water rich 20, 30 years ago, now are discovering that they really are not water rich, they have source supply issues, they have serious questions about how they're going to accommodate additional growth in their communities. melosi: if we can find alternatives, we can preserve a water supply. conservation of water is a way of generating more water. allbee: we think that a household can actually reduce its water usage by about 30%. and that's hugely important in terms of the amount of infrastructure that community's going to require. narrator: las vegas is one of the fast-growing areas in the country. it's a relatively new city under constant construction.
